The Nationals and Phillies collectively decided to postpone Thursday night's game as a way to "call attention to the racial and social injustice that continues to exist in our country."
Both clubs jointly announced the decision, one day after the NBA was forced to suspend postseason play following a player boycott in response to Sunday's police shooting of Jacob Blake in Kenosha, Wisconsin.
The NHL is similarly postponing postseason games scheduled for Thursday, a decision the league arrived at after catching considerable blowback for not acting sooner, with San Jose's Evander Kane saying Wednesday evening, "It's incredibly insulting as a black man in hockey the lack of action and acknowledgement from the @nhl, just straight up insulting."
It's unclear at this time when the game will be made up, as the Nationals begin a three-game series in Boston and the Phillies are set to host the Braves on Friday.
The Nats and Phillies' next scheduled meeting is Monday, Aug. 31 in Philadelphia. The game could be rescheduled for then as a doubleheader, with Philly ceding home-field advantage to Washington for one game.
